A Bayesian Framework for Parameter Estimation in Dynamical Models with Applications to Forecasting

Mathematical models in Biology are powerful tools for the study and exploration of complex dynamics. Nevertheless, bringing theoretical results to an agreement with experimental observations involves acknowledging a great deal of uncertainty intrinsic to our theoretical representation of a real system.
Proper handling of such uncertainties, is key to the successful usage of models to predict experimental or field observations. This problem has been addressed over the years by many tools for model calibration an parameter estimation. In this article we present a general framework for uncertainty analysis and parameter estimation which is designed to handle uncertainties associated with the modeling of dynamic biological systems while remaining agnostic as to the type of model used. We apply the framework to two Influenza transmission models: one deterministic and the other stochastic. The results show that the framework can be applied without modifications to the two types of models and that it performs equally well on both. We also discuss the application of the framework to calibrate models for forecasting purposes.

The "song triptych": reflections on a Debussyan genre

Debussy composed eight sets of three songs between 1891 and 1913. Containing almost all the mélodies of these years, the series tracks his development from post-Wagnerian maturity to ‘late’ style.While we have several fine readings of individual songs, the distinctive ‘triptych’ form of the Debussyan ‘song cycle’ has received little focused analytical attention. One reason might be glimpsed in Susan Youens’s assertion that these little cycles are not as ‘musically unified as [those] of Schubert, Schumann or Mahler’. Indeed the few existing studies of these tripartite sets generally emphasize textual links over musical ones, often in service of a narrowly ‘narrative’ sense of unity.In this paper, I take a fresh look at the various kinds of textual and musical unity on view in this distinctly Debussyan genre. I begin with a contextual glance into visual culture of the time, which saw a striking revival of interest in painted or printed triptychs. Then, in testing how such ‘painterly’ orientation can qualify our sense of multi-part literary and musical form,I outline an allegorical reading of Debussy’s successive triptychs as an evolving response to the pressures of modernist music historiography

Debussy's string quartet in the Brussels salon of "La Libre Esthetique"

The second performance of Debussy's String Quartet, given by the Ysaye Quartet on an all-Debussy program during the 1894 salon of "La Libre Esthétique" in Brussels, offers an ideal context for a critical reexamination of his musical and aesthetic affinities at this pivotal moment. In the first place, a view to the salon's other three concerts, which honored Beethoven alongside recent works by Societe Nationale composers, encourages reconsideration of Debussy's own response to the "great tradition" in the work he ironically designated "Opus 10." But at the same time, due regard to his other contemporaneous compositional obsessions, as exemplified in the works programmed alongside the Quartet, raises the question as to how such self-conscious dialogue with Classical models related to more pressing, post-Wagnerian musical negotiations. Pursuit of this question through analysis of the first movement's reconfigured sonata form ultimately suggests ways to distinguish, from amid the myriad post-Impressionist artists on view in the "Free Aesthetic" salon itself, those painters whose visual explorations most tellingly paralleled Debussy's own "games" with musical syntax and expression in the early 1890s

Code for sustainable homes: opportunities or threats for offsite manufacturing and mass-customization?

This study intends to, firstly, discuss current status of zero carbon homes in the UK, and secondly, to investigate the feasibility of using offsite construction methods to deliver mass customised zero carbon homes. The study concludes that mass customised offsite housing could be an answer to overcome the current barriers to achieve zero carbon homes in the UK; however, more work is required to increase the confidence of stakeholders including clients, designers, and housebuilders in offsite manufacturing in order to increase the share of such methods in the construction industry

Rare Lexical Speech Automatisms in a Case of Progressive Nonfluent Aphasia

The production of aphasic lexical speech automatisms (yes and right) produced by C.S., a man with progressive speech impairment and primary progressive nonfluent aphasia, were analysed across a range of takes varying in complexity. More automatisms were produced during single word and nonword reading and repetition and picture description than during connected reading and counting, suggesting that internally generated (picture description) and externally triggered (single word and nonword reading and repetition) were equally affected. In addition, a complex speech task (connected reading) produced then fewest automatisms than easier ones (single words). However, tasks where there were increased opportunities for disinhibition produced more automatisms. Results do not suggest that the intrinsic or extrinsic motor speech systems are separately damaged, but do suggest that increased opportunities for disinhibition may produce more automatisms

Convolutional-Code-Specific CRC Code Design

Cyclic redundancy check (CRC) codes check if a codeword is correctly received. This paper presents an algorithm to design CRC codes that are optimized for the code-specific error behavior of a specified feedforward convolutional code. The algorithm utilizes two distinct approaches to computing undetected error probability of a CRC code used with a specific convolutional code. The first approach enumerates the error patterns of the convolutional code and tests if each of them is detectable. The second approach reduces complexity significantly by exploiting the equivalence of the undetected error probability to the frame error rate of an equivalent catastrophic convolutional code. The error events of the equivalent convolutional code are exactly the undetectable errors for the original concatenation of CRC and convolutional codes. This simplifies the computation because error patterns do not need to be individually checked for detectability. As an example, we optimize CRC codes for a commonly used 64-state convolutional code for information length k=1024 demonstrating significant reduction in undetected error probability compared to the existing CRC codes with the same degrees. For a fixed target undetected error probability, the optimized CRC codes typically require 2 fewer bits.Comment: 12 pages, 8 figures, journal pape
